Hello, I would like to ask you one question.In the datasheet of NUCLEO-L432KC, MCO output from ST-Link MCU should be used for input clock of L432KC MCU to use/enable HSE option.I wonder if I can use HSE without using MCO output from ST-LINK MCU.I wa...

Or I can add additional circuit for HSE in my customized PCB layout.8MHz XTAL driving circuit. Readout circuit (its output will replace the MCO output from ST-LINK MCU).

Just curiosity.In the datasheet, I can get a more precise frequency if I use 8 MHz XTAL (MCO from ST-LINK).I am working on frequency-related project, so I just want to improve the freq. accuracy.If it is impossible, I have no choice but to change the...

I would appreciate if you could explain the difference between XTAL and crystal oscillator you mentioned.I think they are same, Isn't it?
